6 Claims.

My invention relates to improvements in cleaning devices, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

vAn object of my invention is rtoprovide an improvement over the form of the invention shown in the patent of Charles Lee Boggs and Carl E. Lang, on a Cleaning device, No. 2,054,515, issued September 15, 1936. In Ythe patented `device there is shown a stand for supporting three jars, one vof which contains a cleaning fluid and the I other two contain a rinsing iluid. A basket for carrying watch parts or other articles to be cleaned is shown in the patent, as being connected to a motor shaft. The motor carries a cover member that cooperates with a clamping device carried bythe stand for removably clamping the cover to any one of the desired containers or jars. When the operatordesired to dry the parts after the rinsing operation the motor was'inverted forA disposing the basket above the jar Sor. container. .i

-In the present form of the invention I show four jars or containers placed in a stand. Three of these jars perform the same function as the three-set forth in the patent. The fourth jar or container is preferably of less height than thev others and constitutes a drying compartment.` The basket is placed in this jarand is rotated by themotor for drying the articles within the basket. u

v Inthe patented devicethere is shown separate clamping means for each jar, ythese clamping means cooperating with the cover carried byv the `motor Yfor securing the cover to the jar or container. A In the present form'of thesinvention- I show a standwconsistingof a casting .formed with four recesses .fori receiving the four jars. A second casting is designed to overlie the jars and'is adjustably secured to the iirst casting.

'I'he adjustment is such that the second casting maybe moved vertically toward. or away from the first casting or base, and can be rocked slightly abouta horizontal and longitudinal axis 'Ihe second casting carries cam portions` also. designed to engage with projections which in turn are carried by a cover` supported by the motor. This cover is designed to ,close and seal any one of the three jars containing uid. 'I'he secondcasting contains novel means for supporting the cover whenthe basket'is placed in the drying jar.

--The basket itself is the-form` shown inthe patent and the jaws fr=\either gripping the-basket Vor the Watch I the device;

' are secured` tothe bottom plate and changed slightly from mechanism also are altered slightly. 'I'he means for holding the jaws in extended position has' been changed.

During the operation of the device a portion of the liquid has a tendency to move upwardly along the motor shaft. I provide a novel pack-` ing where the shaft enters the motor, and this packing prevents the liquid from gaining access to the interiorof the motor.

Other objects and advantages will appear in the following specification, and the novel fea' tures of the device will be particularly pointed out in the appended claims. j j

My invention is illustrated in the accompanying drawings forming a part of `this application, in which Figure 1 is a side elevation of the device, portionsbeing shown in section; y y

shaft; and

Figure 6 is' a bottom plan view of the watchor basket-gripping jaws and associate parts.

In carrying out my invention I provide a' standindicatedvgenerally at A. Thisstand isv in the'form of a-casting and. has. a bottom plate I witha iiange'2 extending-upwardly from thev marginal edge of theplate. The ange 2 is curved Vto form container-receiving receptacles indicated generally at v3,and the bottom plate I has its marginal edge similarly curved. 4Pads 4 support the stand A above a supportingrsurface 5.

The top or cover casting indicatedgenerally at Bis provided with downwardly'y extending flanges 6 that are curved for receiving the tops of the jars -or containers indicated generally at 'I, see Figures Land 4. Apartition 8xis disposed between each'curvedportion cfy the'flange. 6, and this partition carries inwardly extending projections 9.v A projection'y I0 similar to, onefof the:`

I5. A wing nut I6 clamps the lower endlofvthe 515i;

upright I2 to the end wall I1 of the casting A in the desired position.

It will be seen from this construction that the casting B can be raised or lowered with respect to the casting A and held in adjusted position by the bolts I5. It is also possible to rock the casting B about the bolts I3 as a pivot if desired, for a purpose hereinafter described.

The casting B is provided with three bottle or jar-receiving compartments as already stated, and sincev allthree of these are identical in construction a description of one will suice. In Figure l I show the jars 1, 1a and 1b closed by the covers I8, I8a and I3b. These covers carry outwardly extending projections I9, I 9a, and I9b that are designed to yieldingly engage with cam surfaces 2D, formed in the casting B, see Figure 4. Each cover also is provided with a gasket 2I and a handle 22. The casting B has recesses 23 for receiving the projections I9, I9a and I9b.

. -It should be noted at this point that the tops of the jars are centered by contacting with the inner cylindrical surfaces of the cams 20 and the inner curved 'edges of the webs 9 and I0. This permits the covers I8 to be quickly centered above the jars. Each cover is moved downwardly when its projections I9 are aligned with the recesses. 23, and then the cover is rotated through an arc of 90 by means of the handle 22. The projections I9 will ride beneath the cam surfaces 29, and this will force the cover down upon the jar, whereupon the gasket 2| will form a liquid-tight seal with the upper edge of the jar.

I will now describe the basket and the motor with its connections for rotating the basket. In Figure 5 I show the basket generally at C. This basket has a bottom and side wall formed from a wire mesh indicated at 24. A compartment 25 is formed in the basket and the bottom and side wall of this compartment also are constructed from a wiremesh material. The top of the basketisencircled by a metal band 26 of the shape shown. The upper edge 21 of this band is struck inwardly at two diametrically opposite points for providing projections 28.

In Figures 5 and 6 I show a basket-gripping member indicated generally at D. This member is in .the form of a disc 29 of a diameter large enough to be snugly received in the top of the basket C.` The periphery of the disc has recesses 30 for receiving the inwardly extending projections 28 of the basket. The disc carries two jaws.3Iv and 32 and these jaws have shanks Slay and` 32a slidable in bores 33 and 34 formed in the disc 29. One edge of .each shank 3Ia and 32a is. provided with ratchetteeth 35, and these` teeth mesh with a central pinion 36 mounted within the top and bottom walls of the disc 29. The pinion is made fast to a shaft 36, see Figure 5. It will be seen that a rotation of the shaft 36 with respect to the disc 29 will rotate the pinion 36 for moving the jaws 3l and 32 toward or away from each other. When the jaws are moved away from each other the shanks 3Ia and 32a uncover the recesses 3D. This will permit the disc 29 to be placed at the top of the basket andthe recesses 38 will receive the projections 28. Novel means now to be described will move the jaws 3I and 32 toward each other, and this will cause the ends of the shanks 3Ia and 32a to move beneath the projections 28 and lock the disc 29 to the basket.

Figure 6 .shows the disc 29 provided with openings 31 Ato allow the free passage of fluid theregthrough..

The means for urging the jaws 3I and 32 toward each other and for locking the jaws in any desired position is illustrated in Figure 5. A cap 38 is rotatably mounted on the shaft 36 and carries a sleeve 39 that has a cam outer edge 40. A collar 4I with a cooperating cam edge 42 is secured to the shaft 36 by means of a pin 43 or other suitable fastening means. A spring 44 is mounted within the cap 38 and has one end secured to the shaft 36 at 45, while its other end is securedto the disc 29 at 46.

It will be seen from this construction that a rotation of the cap 38 in the direction indicated by the arrow a in Figure 5 will cause the shoulder 42 of the sleeve 39 to engage with the shoulder 49' of the collar 4I for rotating the collar and the shaft 36 in the same direction. The disc 29 is held against rotation during this movement, and therefore the pinion 36 will move the jaws 3l and 32 away from each other and retract the Shanks 3Ia. and 32a.. This will free the Shanks from the projections 28 and permitA the disc 29 to be .removed from the basket.

When it is desired to use the jaws 3I and 32 for gripping a watch movement, not shown,=in

stead of the basket, the cap 38 is rotated .in the direction of the arrow a with one hand while the disc 29 is held against rotation by the other hand.

The rotation is continued until the' jaws 3| andv 32 are extended suiiciently to receive the watchv The shaft 36 is then held against.

ing of the jaws from .the watch movement.-

In Figures 1 and 5 I show the shaft 36 enter-'- ing a packing indicated generally atv E. This packing comprises an inverted cup-shapedzmember 41 mounted on a motor shaft 48. Afnipple 49 is threaded into the lcup-shaped member. .41,- and clamps a retainer 50 against the gasket 5I.1

The gasket in turn is mounted in a cover 52 that is secured to `a casting 53 which supports a motor 54. The shaft 36 enters the nipple 49v and is spaced from the wall thereof. The shaft 36 also is provided with a bore 55 for receiving'f the motor shaft 48. The two shafts 36 and .48 are connected together to rotate as a unit.fThe'E cover 52 is of the same size and shape as the` covers I8, I8a and I8b, and may take the place of any one of these covers. A portion of-theliquid when rotated by the basket C will have a tend ency to move upwardly on the shaft'36 in the form of foam. This foam upon entering the.- nipple 49 will be changed into a liquid, and ythis liquid will gravitate along the outer surface of Y the shaft 36. In this way the packing E preventsthe liquid from gaining access to the motor 54. A washer 41 is mounted at the top of the member 41 and prevents any liquid entering the motor `The; cap is then freed and the spring 44 will rotate',

The fric; tion is such as to prevent the accidental release" agosgecof In.y Figure-1 II show .me v(gisting 53 providedwith a handle 56, and this handle extendsover f. the motor 54. The handle may be rotated for mov'ingthe lugs 52 in' thecover 52 beneath the cam edges 20 for securing' the cover to one vofthe jars. When the basket C is placed in the drying jar 51 the cover 52 will rest on Va ring 58 that isfsupported by the inwardly extending portions 9 and ID of the casting B. The cover 52 in this instance does not close the jar 51, and thereforel air is free to enter and leave the jar during the drying operation.l

A switch 59 is mounted in the handle 56 and this switch is protected so that any spark is confined within the handle 56. This is to prevent any fire from accidentally taking place due to fumes rising from the cleaning uid. The motor 54 is an induction motor, and this also obviates anyl fire hazard due to the sparking.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

If an entire watch mechanism is to be cleaned the basket is dispensed with and the jaws 3l and 32 grip the watch and secure it to the disc 29. The cover I8 now is removed and the Watch mechanism is inserted in the jar 1. It should be noted that the axis of the motor and the watch mechanism is eccentric to the axis of the jar 1 in the same manner as set forth in the copending application. The handle 56 connected to the motor is rotated through an arc of and this will cause the lugs 52 to cam beneath the cams 2U and to seal the cover 52 on the jar 1. The motor is now started by closing the switch 59 and the watch mechanism will be rotated in a cleaning iuid 60 disposed within the jar. The rotation of the watch mechanism will cause the uid to rotate and the vortex of the uid will coincide with the axis of the jar. This will dispose the mechanism. eccentric to the vortex with a result that the parts to be cleaned will be immersed in the liquid frequently enough to prevent oxidation.

When the basket is connected to the motor and placed Within the jar, the rotation of the basket will create a vacuum along the axis of the basket which will draw the fluid into the basket. This fluid will be thrown out through the side Wall of the basket by centrifugal force. This fluid in moving through the basket cleans the watch parts. It should be noted that the center line through the basket affords an unobstructed path for the fluid.

After the parts have been cleaned the necessary length of time, the handle 56 is rotated for removing the cover 52 from the jar 1 and then the watch mechanism. or basket also can be removed from the jar. The basket is now inserted in the jar 1a after the cover I 8a has been removed. The cover 52 is locked to the jar 1a in the manner already described. The basket C is disposed eccentrically to the jar 1a and a rotation of the basket caused by the motor 54 will rinse the parts in the rinsing iluid 6l disposed in the jar. A second rinsing fluid 62 is disposed in the jar 1b, and the basket is replaced in the jar 1b after the rinsing operation in the jar 1a.

The parts are now ready to be dried and the basket is placed in the jar 51. The cover 52 is clamped to the ring 58 and then the motor 54 is connected to the source of current by the switch 59 for rotating the basket. When the parts are dried the basketmay be removed'from the jar 51 'and then may be disconnected fromthe'disc 29. The cleaned and dried watch parts within the basket are now ready to be placed back in the watch mechanism.

By mounting the casting B on bolts I 3'it is possible to rock the entire casting to accommodate the covers I8, |8a and I8b and also'the cover 52` with the jar tops. Better sealing results and this prevents leakage during the operation of the device. As already stated the casting B may be adjusted vertically to accommodatebottles or jars of vdifferent lengths or heights. The packing E provides a novel manner for seal ing the motor against the entrance of foam. The foam` is broken down before it reaches the top or" the cup-shaped member 41. The handle 56 not only moves the motor from place to place, but also is used for rotating the cover 52 through a 90 angle when locking the cover in place to a jar or removing it therefrom.

, The jaw locking device D is simplified so that the basket C may be quickly attached to or removed from the disc 29.` The purpose of the small jar 51 is to catch the liquid thrown oil by the basket during the drying operation. The

basket is provided with a small compartment 25 for receiving the small watch parts. The bigger parts may be placed in the bottom of the basket and these are centered with respect to the axis of the basket so that during a rotation of the basket a less vibrating effect will result.
